Old English blæc, of Germanic origin
Black has been used to refer to African peoples and their descendants since at least the late 14th century. Although the word has been in continuous use ever since, other terms have enjoyed prominence too: in the US coloured was the term adopted in preference by emancipated slaves following the American Civil War, and coloured was itself superseded in the US in the early 20th century by Negro as the term preferred by prominent black American campaigners such as Booker T. Washington. In Britain, on the other hand, coloured was the most widely used and accepted term in the 1950s and early 1960s. With the civil rights and Black Power movements of the 1960s, black was adopted by Americans of African origin to signify a sense of racial pride, and it remains the most widely used and generally accepted term in Britain today. In the US African American replaced black in many contexts during the 1980s, but both are now generally acceptable.
